To all whom it may concern: 5 adapted to engage the spaces between Beit known that I, EDWARD B. Hess, a the teeth on the upper surface of the bar citizenlof the- United States of America, re-

city, l New York, have inl Vented a certain new and useful Improv'e- 5 of which the;

new organization :wherein margin paper-holding v-or clamping devices are; adjustable simultaneously with margin stop devices and -in the devices are mounted upon. the margin stop devices.

drawing: Figure 1 l is a vertical longitudinalsection oiso much-l of a front strike typewrlting' ,macluneas s ing or clamping deemed desirable to illustratefthe invention: Fig. 9., a rear elevation: Fig. 3,a deta'xl plan 3 view of combined margin stop and margin paper-clamping devices: and Fig. .4 area! elevation of a margin stop device, t e mar-l gin paper-holding devices not being shown in this view. I 3 p X and Y indicate the side or end [plates the rack'bar and S .the ordinary e \j'lind rioa lplaten mounted to turn in the and plates. platen, there is mounted in the end plates a rack bar-N having coincident and equally spaced teeth on i upper and rear surface. On this'bar are adi justahly, mounted right and left hand mari gin stops K and intermediate stops M that may be used for tabulation purposes.

J is the center or frame stop pivoted upon the frame at 3' and adapted to he moved stop is so arranged as of the adjustable stop brace and closely fit in "thequpper The-margin stops may each be constructed l "as follows:

transversely of the rack bar N. Tn the particular construction illustra'tedfthe center to be out of the path M but. in the path of the margin stopsK. The; intermediate or tabular stops M are bifurcatedj so as to emthe spaeesihetween i and side teeth of the raclrahar.

and is held in 'posi straddles the rack bar tion thereon'by cross pins is extending be neath the bar b'etw'een lugs on opposite sides of-th'e frame. The-part-of the stop against which abuts theframe, stop lever J"is the head is: ,of an adjustable screw turning in a threaded ope ina lateral projection or block on'oneof the of the frame K and having applied toi'ts threaded end a lock nut k; A beveled plate kcarried on the upper surface/of the'projection in which the screw is mounted serves to snub the st p lever-out of theiwaywhen the-carriage is moved in one direction whereas the stop lever. J is engaged carriagemoves in the other'direction- The stop lever J is shown'as astraight lever and below its pivot-it fits between the arms of a rockin bifurcated arm'O fast 0n a rock shaft pivoted in the frame of the machine and having at its right head end a n upright promotion '0? attached by" a linl:

to a vertically disposed lever arm 0* board of'themachine. Springs 0, 0, hearing In rear of the respectively upon opposite sidesot the vertically disposed bifurcated part 0 tend to maintain it in central or'vertical position.

" Above the pivot 1 of stop lever J, the latter has an adjustable screw 0 that engages the lower end of; a rack releasing lever I, whose upper end hes under a horizontal flange of the escapement or feed rack S ofthe machine. This rack is carried in the ends of level-=- s s pivoted at a on the side plates of the carriage and having applied to their ends springs s the reaction of which tend to hold the rack inengagement with the pin ion 5 of the escapcment. devices. When lever arm 0 is drawn to-thefront. tho upper end of stop lever J is rocked away from the stop bar N. This movement is of such extent as to disengage the lever J from the part is of the marg'm stop to therebyperxmt of the writing of one or more letmg work this mo lever. J ata sugble-point; above the pivot j of the latterisa plateiPf whoseaxis p is'at' right angles to; aXi's' plate extends upwardly substantially as far as.the stop lever land is normally held away from the latter by re-actionsprmg 1). An extension P from plate P extends a suitable distance below its pivo't and is connected by link P with a radial arm Q, on the upper end of a,

vertical rock shaft Qfi having near its lgwer end a-radial arm Q fromwhich' extends forward a link Q connected atits front end, with a; radial arni q"onftransverseicfk' shaft This rock shaft'q has extending upward from ita key lever locking late 9 an'dlock them against operation.

. shaft fg that; will carry' the locking plate 9 orward from a-Wertical'line. e

R indicates a character key lever of which there'iivill be the usual number. Near the frontend of each key lever is a downward projection r the front edge or corner of which is closely adjacentthelocking late q. Whenthe stop J P is'engaged by either a margin stop or atabular stop when the carriage-is hio'ving during the progress of which normally isinelined slightly the printing operation, plate P'will be car- "ried against the side of stop J and in 1ts movement will.- efi'ect a movement of rock -under'"th'e projections 1' on the key levers The paper table in the special construction illustrated is divided into tu'qb parts a hinged upper part U and'a fixed lower part. Ui Between the two parts of the taljge there is an o ning u which isopposite r horizontally 111 line with the front side or face of the frames of'the right andlefthand margin stops. 'Securrel, to and projecting from each margin sto -framea plate .or arm V thatextends tirou'gh thetransverse opening u. Hinged to this arm at v is a margin paper clamp consisting ofan arm W extending forward over and around the.surface of the platen. In this armis'preferablv placed a pressure or margin paper clamp roll W bearing upon the platen and in rear of which is a recess-W in whichthe edge. of the paper that is being printed upon traverses. In rear of the hinge b there is fastened to the: upper surface of the-arm ""i leaf spring-z that extends over the hinge and bears upon the plate V and by its reaction serves to m me paper clamp or pressure roller lvf'aga'inst the surface of the -plati' \Vhen, howjerer, the paper clamp, is swungupwardly upon its llipge'out of the ava g'or into inoperative position, theend of the springgghpasscs inth an aperture 1: in

- sw ung suliiciently far back, the reaction of the spring tends to hold the paper clamp in elevated position, In order that the opera Julie-plate or arm W and when the arm is' torm'ay adjust-the margin stop and with it i "the margin paper-clamp without reaching back to the body of the stop and without disturbi'ng the hinged portion U of 1e paper table, there is provided a lever Z ivoted upon the outer side of the arm or plate V and projecting rearwardly through the transwse opening U in the pa er table,"

Qnthe ends of spring latch K o the marfgin stop, there is a projecting pin 2 that overlies lever Z. By depression, therefore, of the lever, the latch may be disengaged stop and with it the paper-clamp be adjusted longitudinally of the stop bar and from the'toothed stop bar and the margin 7 platen. This arrangement by which the margin paper clampand themargin stop may be simultaneously adjusted is believed i to be a novel feature in writing machines" and has manifest advantages. The construe.

tion illustrated moreover possesses the;

further advantage that asingle transverse stop bar is made to serve both as a support; for the margin 'stop and for intermediate or; tabular stops as well as for paper margin:

clamps. 1 The invention is shown applied to a froiit strike machine. It is, however, not re stricted to machines of that type.

This application is a division of my apfi plication filed May 15, 1907 Serial Number $73,849.

No claim is made herein to the special line hock devices which form the subjectmatter of another application. T

I claim:

luThe combination of a typewriter 'car- .riag, jg: laten mounted therein, a paper table divided longitudinally of the platen with a space between its adjacent edges, an

adjustable margin stop located behind the'f paper table, and a margin clamp devicegmounted on the margin stop and extending: through the opening in the paper table into paper table, an arm attached to the-margin,

stop and extending through the opening in the paper table and .a margin clamping member hinged in the end of said arm.

3. The combination of a typewriter carriage, a platen mounted therein, a paper table, an adjustable paper clamp, means at the rear of said paper table for supporting said clamp, locking meansfor securin said clamp in an adjusted position on sai supporting means, and releasing devices for 10 said locking means, said releasing devices extending in front of said paper table.

In testimony whereof, I have hereunto subscribed my name.

EDWARD B. HESS.
